25. Impersonation in data access
WMS/WFS
client
GeoServer
GeoServer user: X
DBMS
Connection pool user:
impersonating DBMS user X
 Use the current
GeoServer user to
access DBMS
contents
 Tighten security also
at the DBMS level

security setups

SDI Days 2013, Sibenik
27th September 2013

27. Improved Raster Reprojection

transformation with a simpler
one, either a single affine
transformation or a piecewise
composition of them (grid warp)
 Ability to specify threshold for error
acceptance
 Iterative approach (local optimization)
 Trade off between speed and
precision
